How do I get a sequence of code to repeat?
For example, I entered:

spe
lef 1051 790 "Internet Explorer"; 0.78
lef 1282 825 "Internet Explorer"; 0.42
lef+ 1279 825 "Internet Explorer"; 0.27
lef- 1275 821; 1.13
lef 978 611 "Internet Explorer"; 1.34
lef 966 649; 0.63
lef 1048 612 "Internet Explorer"; 3.64
lef 559 499 "Internet Explorer"


And I want that sequence to repeat it self, can someone help me please?
